APPARATUS FOR'HUMIDIFYING AIR.

SPECIFICATION forming part of Letters Patent No. 642,992, dated February 6, 1900.

Application filed April 23, 1898.

T0 (0% whom it may concern:

Be it known that I, JOHN J. MANN, a subject of the Queen of Great Britain and Ireland, residing at Paris, in the Republic of France, have invented new and useful Improvements in Apparatus for Humidifying Air, of which the following is a specification.

This invention relates to apparatus for humidifying air, the object being to improve the action and construction of such apparatus.

In the accompanying drawings, Figure 1 is a vertical section of my improved humidifier. Fig. 2 is a vertical section of a part of the same, drawn to a larger scale; and Figs. 3 and 4 are views of modifications.

My improved apparatus comprises an outer cylinder 1) open at both ends, as usual, and an inner cylinder b combined with two spraying devices for throwing two line sprays in conical form one against the inner face of the outer cylinder and the other against the inner face of the inner cylinder, as indicated at 00 and 0c in the drawings.

The cylinder 1) is provided with an outwardly-fiaring or trumpet mouth b at its lower end, and I prefer to form a gutter b v around the lower edge of this month to catch any water running down the inside of the cylinder and prevent its dripping from the edge of the mouth b A pipe or duct d,fish-backed in section-that is, with a sharp upper edge carries oif the water from this gutter b into the bottom of the dish 0, which is suspended below the cylinder 1). Above this dish 0 and with its upper end projecting into the mouth of the cylinder 1) is a spraying-cone c for dispersing the line spray into the room.

The water is supplied to the spraying devices at the nozzle a, which is arranged centrally in the cylinder 1) near its upper part. It may be suitably secured by a coupling H to a bridle or cross-bar M, fixed to the top of the cylinder, as shown in Fig. 1. The nozzle Ct has at its lowerend a small opening, through which projects a spindle a, having at its upper end. a head or shoulder 0. within the nozzle. Centrally below the nozzle a is a second nozzle a connected with the first by the curved branch pipe 19. The rod a, which carries the head or shoulder a within the nozzle a, has below the opening in the nozzle a a second shoulder a which normally stands in such a Serial No. 678,596. (No model.)

position in relation to the opening in the nozzle as to cause the waterissuingfrom the nozzle to be broken up into fine spray in the conical form indicated by dotted line w, striking against the inner face of the outer cylinder 1). In like manner this same rod has Within the box a a head or shoulder a, the rod passing through a stuffing-box a and just below the opening in the nozzle a it has a shoulder a, which, like the shoulder a causes the water issuing from the nozzle a to be broken up into fine spray in a conical sheet, as indi cated by dotted line m, and striking against the inner cylinder 5 The spindle which car ries the described shoulders passes down through the box or casing A. Beneath and within the box is a spiral spring a which tends to press the spindle upward and maintain it in the position indicated in Fig. 2. The spindle below the box A is provided with a suitable abutment, such as a nut a adj ustably threaded onto the spindle, so as to insure the correct positions of the shoulders a and 04 below their respective nozzles. From the lower end of this spindle a hangs a cord, chain, or such other device a, preferably provided withasuitable handle a Fig. 1, so that bypulling on this handle the head a and the head (L can be brought down to the orifices of their respective nozzles, so as to clear out dirt from such orifices. These heads a and a may be such that when the cord is pulled down not only will the orifices be cleared of dirt, but the flow of water can be stopped thereby any desired length of time by hooking or fixing down the handle a or cord a when drawn down. When the cord a or handle a is released, the spring a will return the shoulders a and e on the spindle a into their proper places to form the conical sprays, the nut a or other abutment insuring the correct positions of said shoulders.

The dish 0 carries an upwardly-projecting tube I), open at the top and bottom and placed centrally in the apparatus and extending up through the spraying-cone c. This tube is for the passage of the cord, chain, or other device a and is to protect it from the moisture. As a further protection the lower end of the spindle a is provided with a dome, cone, or other cover a protecting the upper end of the central tube b and preventing water from falling into it. At the lowest part of the dish a is an escape-pipe e for the water collecting in or on the inner surface of the apparatus or delivered from the pipe d.

The inner spraying-cylinder b maybe short, as indicated in Fig. 1, or it may be made considerably longer, as indicated in Fig. 3, and

'with a flaring month 19 which will serve to disperse the outer spray or, the inner spray 00 being dispersed by the cone 0' on the dish 0 beneath. If preferred, this cone b as shown in Fig. 4, may be placed at such a distance above the flaring mouth 19 011 the cylinder b as to deliver the two sprays w and as in more distinctly separate strata or planes, having unhumidified air between them which can take up excess of moisture from either spray. A gutter f will be provided at the lower edge of the inner cylinder 17*, whether itis splayed out or not, to catch the water from both surfaces of the internal cylinder b This gutter may be drained by a pipe (V, Fig. 4, in the same manner as the gutter b is drained.

By the use of two conical sprays breaking against the inner faces of two concentric imperforate cylinders in the manner described. I am enabled to prevent the formation of drops of water, which have hitherto'diminished the utility of double sprays in one cylinder and which I have found are formed by mingling or crossing of the sprays in the apparatus as heretofore constructed.

I claim as my invention- 1. The combination ofa humidifying apparatus comprising an outer casing and an inner casing and two spraying devices for throwing conical sprays one against the inner surface of one cylinder, and the other against the inner surface of the other cylinder without mingling of the said sprays, substantially as described.

2. A spraying device consisting of a chamber, an opening in the end of said chamber, a spindle passing through said opening and provided with a head a within said chamber and a shoulder a outside said chamber, a spring to press the spindle upward, an adjustable stop fornormally holding said shoulder a at the desired distance from the said opening and means connected to the lower end of said spindle for moving it against the action of the spring whereby the head a may be caused to close said opening, substantially as and for the purpose described.

3. A humi'difying apparatus comprising a casing, a water-nozzle with a spring-pressed spindle having a head-01. within the nozzle and a spraying-shoulder a outside the said nozzle, a cord or chain for pulling the said spindle downward against the action of the spring and a tube b covering and protecting the said cord, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
